BACKGROUND OF THE INVENTION

At present, the space structure of a refrigerating compartment of a refrigerator generally comprises one or more shelves. Different kinds of articles may be stored on one shelf at the same time. However, as the weights of articles stored on the shelf cannot be obtained intuitively, a user needs to open the refrigerator to observe and estimate the articles on the shelf and thus cannot obtain the number and weights of the articles accurately.

In addition, different kinds of articles stored in the refrigerator usually have different shelf lives. At present, the user can only infer the states of the articles by memorizing the time of placing the articles and the shelf lives thereof, but misjudgment can easily occur just by memorizing the above information. In the prior art, it is also possible to record the time of placing articles manually. However, this method is cumbersome and may not intuitively suggest what state the article is in at the same time.

In light of the above-mentioned problems, it is necessary to provide a shelf system and a control method thereof to solve the problems.

In addition, it should be noted that in order not to obscure the present invention by unnecessary details, the accompanying drawings only show the structures and/or processing steps closely related with the technical solutions of the present invention, while other details not closely related therewith are omitted.

Further, it should be noted that the terms “comprise”, “include” or other variants intend to include the listed elements in a non-exclusive manner, so that the processes, methods, objects or devices including a series of elements not only include such elements but also include other elements not clearly listed, or the inherent elements of such processes, methods, objects or devices.

As shown in FIG. 1, a shelf system 100 in a first embodiment of the present invention comprises:

a shelf main body 11 configured to store an article;

a weight sensing device 12 which is disposed on the shelf main body 11 and may be a pressure sensor or other device configured to detect a weight; and

a processor 13 which is connected to the weight sensing device 12 and configured to record weight information of the stored article recorded in the weight sensing device. Meanwhile, the processor 13 is further provided with a clock unit (not shown), such that the storage time information of an article may be recorded in combination with the clock unit. The processor is further provided with a preset time interval. The processor may determine the state of the article just by comparing the time information with the preset time interval.

The shelf system further comprises a display device 14 which is connected to the processor 13 and configured to display the weight information and state of the article stored on the shelf main body 11.

Correspondingly, FIG. 2 illustrates a control method for a shelf system in the present embodiment, which comprises the following steps: S1, acquiring weight information of an article stored on a shelf main body; S2, recording storage time information of the article on the shelf main body; S3, acquiring the weight information and the storage time information of the stored article, and determining a state of the article in accordance with a preset time interval; and S4, displaying, by a display device, the weight information and the state of the article stored on the shelf main body.

Specifically, the determination and display method for the state of the article in the present embodiment includes: defining the preset time interval set in the processor as [T1, T2] and the storage time information of the article recorded by the processor as T. The state of the article determined by the processor just by comparing the time information with the preset time interval includes: a first state in which the storage time information T of the article is less than T1; a second state in which the storage time information T of the article is not less than T1 and not greater than T2; and a third state in which the storage time information T of the article is greater than T2.

Correspondingly, colors of the first state, the second state and the third state displayed on the display device are a first color, a second color and a third color respectively.

For example, with respect to an article, the preset time interval may be [5 days, 10 days]. The processor updates the time information T on the stored article in real time. If the storage time information T is less than 5 days, it is determined that the article is in a fresh state, and the display device displays a green color correspondingly. If the storage time information T is not less than 5 days and not greater than 10 days, it is determined that the article is not in a fresh state, and the display device displays an orange color correspondingly. If the storage time information T is not less than 10 days, it is determined that the article is in an expired state, and the display device displays a red color correspondingly. The user may monitor the article stored on the shelf in time in accordance with the colors displayed on the display device, and remove the expired article in time to prevent it from getting moldy and rotten.

At the same time, the display device may also display the weight information of the article stored on the shelf in real time, so that the user may monitor the weight information of the article on the shelf in real time to avoid the adverse effects caused by the excessive storage of articles on the shelf.

As shown in FIG. 3, a shelf system 200 in a second embodiment of the present invention comprises: a shelf main body 21 configured to store an article, a weight sensing device, a processor 23 and a display device 24.

The present embodiment differs from the first embodiment in that the shelf main body 21 comprises a plurality of storage compartments. Preferably, a description is made by taking three storage compartments as an example in the present embodiment. The shelf main body 21 comprises a first storage compartment 211, a second storage compartment 212 and a third storage compartment 213.

The weight sensing device is disposed on the shelf main body 21 and may be a pressure sensor or other device configured to detect a weight.

Correspondingly, each storage compartment in the present embodiment is correspondingly provided with a weight sensing device, including a first weight sensing device 221, a second weight sensing device 222 and a third weight sensing device 223 which are disposed in the first storage compartment 211, the second storage compartment 212 and the third storage compartment 213 respectively. The first weight sensing device 221, the second weight sensing device 222 and the third weight sensing device 223 are used to detect the weight information of the articles respectively stored in the first storage compartment 211, the second storage compartment 212 and the third storage compartment 213.

The processor 23 is connected to the first weight sensing device 211, the second weight sensing device 222 and the third weight sensing device 223 respectively and configured to record the weight information of the stored articles recorded in each of the first weight sensing device 211, the second weight sensing device 222 and the third weight sensing device 223. Meanwhile, the processor 23 is further provided with a clock unit (not shown), such that storage time information of the articles on each of the first storage compartment 211, the second storage compartment 212 and the third storage compartment 213 may be recorded in combination with the clock unit. The processor is further provided with a preset time interval. The processor may determine the state of the article in each storage compartment just by comparing the time information with the preset time interval.

The display device 24 is connected to the processor 23 and configured to display the weight information and state of the articles stored on the shelf main body 21.

Correspondingly, the display 24 in the present embodiment comprises a first display area 241, a second display area 242 and a third display area 243. The first display area 241, the second display area 242 and the third display area 243 are used for displaying the weight information and state of the articles stored in each of the first storage compartment 211, the second storage compartment 212 and the third storage compartment 213 respectively.

A control method for a shelf system in the present embodiment comprises the following steps: S1, acquiring weight information of an article stored in each storage compartment of a shelf main body; S2, recording storage time information of the article in each storage compartment of the shelf main body; S3, acquiring the weight information and the storage time information on the article stored in each storage compartment of the shelf main body, and determining the state of the stored article in accordance with a preset time interval; and S4, displaying, by each display area of the display device, the weight information and the state of the article stored in each storage compartment of the shelf main body.

Similarly, in the present embodiment, with respect to the first storage compartment, the preset time interval set in the processor may be defined as [T1, T2] and the storage time information of an article recorded by the processor is defined as T. The states of the article determined by the processor by comparing the time information with the preset time interval include: a first state in which the storage time information T of the article on the first storage compartment is less than T1; a second state in which the storage time information T of the article on the first storage compartment is not less than T1 and not greater than T2; and a third state in which the storage time information of the article on the first storage compartment is greater than T2.

Correspondingly, colors of the first state, the second state and the third state displayed on the first display area of the display device may be a first color, a second color and a third color respectively.

Similarly, the states of the articles displayed on the second display area and the third display area in the second storage compartment and the third storage compartment may be the same as those displayed on the first display area in the first storage compartment, and will not be repeated here again.

Further, a user may store different kinds of articles, which usually have different shelf lives, in different storage compartments. As such, it is necessary to set different preset time intervals for different storage compartments. For example, the first storage compartment may store an article with a relatively shorter shelf life, and the preset time interval may be set as [1 day, 2 days]. The second storage compartment may store an article with a normal shelf life, and the preset time interval may be set as [5 days, 10 days]. The third storage compartment may store an article with a long shelf life, and the preset time interval may be set as [30 days, 50 days]. As such, the articles on the shelf may be monitored more conveniently.

It should be understood that a description is made in the present embodiment by taking the three storage compartments and the three display areas on the display as an example. The number of the storage compartments on the shelf main body and the number of the display areas on the display device may be set as other numbers in other embodiments according to user requirements, which will not be described here by way of example.

Compared with the prior art, the present invention has the following beneficial effects: by acquiring the weight information on the article using the weight sensing device, recording the storage time information of the article, processing the above-mentioned information using the processor and displaying the weight information and the state of the article on the display device in real time, a user is reminded of article placement information to prevent the article from going moldy and rotten.
